After the Great pressure is an acute angle I2 is a binding the edges ofthe metal lath binding I2 has placed over the edge of the then appliedto the U-shaped binding l2. This great pressure clamps or binds thebinding material I2 on the expanded metal ll. As the pressure is appliedto the U-shaped binding forcing the two legs of the'binding closertogether the expanded metal '5 is somewhat flattened. This flattening ofthe expanded metal causes the sharp edges l3 to dig in or'cutin thebinding 12. Fig. 2 shows how the grooves I 4' have been cut in thebinding ma terial by the edges 43.

Any tendency for the binding material l2 to spring apart is counteractedby the tendency of the compressed expanded metal H to return to itsoriginal position. After the binding is clamped to the expanded metal ormetal lath 5 it is practically impossible to remove the binding. Anyforce tending to remove the binding from the expanded metal causes thepoints of the expanded metal to grip or dig in. the notches or groovesl4 more firmly. Thus it will be noted that the greater the force exertedon the binding tending to remove it the greater the resistance.

Figs. 3 and 4 show a modification of our invention. The binding l2 hasan integral portion l5 extending at right angles to the plane of theexpanded metal. This extended portion l5 has various uses. It addsstrength to the binding. In connection with the floor mat shown in Figs.3 and 4.- it may be used for a foot scraper in addition to the sharpedges l3 of the metal lath ll.

Fig. 5 shows a fire screen embodying our invention. Several pieces ofexpanded metal are bound in accordance with our novel idea, as shown inFig. 2. These pieces are hinged together by means of rings IS. The unitmay be finished in various ways and various decorations added to make itattractive.

Fig. 6 shows how the ends of the binding may protrude beyond the end ofthe expanded metal. The unit shown in Fig. 6 makes an ideal screen doorprotector. The protruding ends of the bindingare used to fasten the unitto the frame of the screen door.

While we have described several embodiments 4.5 of our invention, we donot wish to be limited to the particular forms shown and described as itwill be apparent that many modifications therein may be made withoutdeparting from the scope of our invention as set forth in the appendedclaims.

Having thus described our invention, what we claim is:

1. In combination, a sheet of expanded metal lath and a U-shapedbinding, said binding being fastened to said expanded metal lath bymeans of pressure, whereby the sharp edges of the flat portion of saidmetal lath, which form an acute angle with the plane of said expandedmetal lath cut into said binding.

2. In combination, a sheet of expanded metal lath, a substantiallyU-shaped binding, and the opposite side portions of said U-shapedbinding pressed so that the sharp edges of said expanded metal lath aresubstantially embedded in said binding.

3. In combination a sheet of metal lath, a substantially U-shapedbinding, and the opposite side portions of said U-shaped. bindingpressed so that the sharp edges of said metal lath are substantiallyembedded in said binding whereby a force tending to pull said bindingfrom said metal lath will tend to cause the sharp edges to cut deeperinto the binding.

4. In combination a sheet of expanded metal lath and a frame comprisingsideand end bars each composed of a plate folded longitudinallysubstantially midway between the longitudinal edges thereof and theopposite side portions of the foldv pressed so that the sharp edges ofsaid expanded metal lath are substantially embedded in said binding.

5. In combination a sheet of expanded metal lath and a frame comprisingside and end bars, each composed of a plate folded longitudinallysubstantially midway between the longitudinal edges thereof and theopposite side portions of the fold pressed so that the sharp edges ofsaid expanded metal lath are substantially embedded in said binding,whereby said sharp edges tend to cut deeper into said frame when a forcetends to pull said frame from said expanded metal lath.

6. In combination a sheet of expanded metal lath, a U-shaped binding,said binding being fastened to said expanded metal lath by means ofpressure, whereby the edges of the flat portions of said expanded metallath which form an acute angle with the plane of said expanded metallath, cut into said binding in such a manner that a force tending topull said binding from said expanded metal lath will tend to twist saidflat portions in such a manner that they tend to cut deeper into saidbin-ding thus holding the binding more securely.

7. In combination a sheet of expanded metal lath and a substantiallyU-shaped binding therefore, said binding being uniformly pressed overthe edges of said expanded metal lath, whereby all the sharp edges ofsaid expanded metal lath which come in contact with the binding aresubstantially embedded therein.
